The Paris Saint-Germain trainer believes his team could still slump to another disappointing run if the team does not keep up its improved performances after consecutive wins.
Les Parisiens slipped from the top of Ligue 1 after defeats to Saint-Etienne, Rennes and Nice during November and early December, but Ancelotti is confident that his players have learned from those performances and would have the strength to overcome another slump in form.
"We have shown a good reaction after the defeat to Nice. We won against Porto and had a good game against Evian. Things are good right now," he told RMC Sport, ahead of the club's match against Valenciennes on Tuesday. "But the Valenciennes match will be difficult, and the Lyon match on Sunday too. It will be a tough week for us. But the team is in a good form.
"I know football very well. A difficult time can still happen. We must not forget what happened during the match against Saint-Etienne, Nice and Rennes. But the attitude we showed in the last two games we have not shown before. It can help us to overcome difficult times."
The former Chelsea trainer has recently changed his side's formation to a conventional 4-4-2, meaning that there is a lot of competition in the center of midfield, but the Italian believes there is not a first-choice pair in the middle of the pitch.
"With the new system, it is true that there is a lot of competition between Thiago Motta, [Clement] Chantôme, [Blaise] Matuidi and [Marco] Verratti," he said. "It will not be easy to choose the two midfielders.
"Verratti has more quality in the construction of the game and Chantôme is a very dynamic midfielder. Matuidi is very aggressive and Motta is one who has the most experience. They can all play together."
Reports in the media have suggested that winger Nene could be on his way out of Parc des Princes, but Ancelotti has said that the former Monaco man has not requested a transfer and remains a member of the squad for the time being.
"If he demands to leave the club, we will make a decision. For now, Nene did not ask to leave the club, so we have not decided anything."
